I've read that the stock plastic 2nd gen SOHC intake is actually pretty good, and I've read about how the Magnum intake works and why it is how it is.

Given an otherwise equal engine setup, how does a plastic intake compare to the Magnum intake on the dyno? I believe it's only over 6000 rpm that the Magnum is better, but even then not by a whole lot.

If we need to be specific about the engine for comparison purposes, let's say it's a stock Magnum engine with a ported and polished Magnum head, Crane 12 cam, and Pacesetter header. So stock ASIDE from these listed mods.

The 1gn plastic IM has been dyno proven to make more overall power than the Magnum IM. There is a thread on it somewhere.

The Magnum IM is also much heavier than the plastic IM. If only they had made it from plastic...

After seeing the dyno results, I have lost most of my ambition to install the Magnum IM over my Ghetto Blaster 1gn full length runner manifold. I have a strong feeling the Mag IM will be a downgrade.

At least with a 60mm TB on either. With the stock TB, possibly the Magnum might have the advantage. But once you get the feel for a 60mm TB, there is no satisfaction in going back to stock._________________Bill
